在android中解析11MB的大json[关闭]

我在使用 GSON 和 Jackson 在 android 中解析大约 11MB 的大 JSON 时遇到问题。问题是发生内存不足错误异常，并且堆大小不足以完成此过程。 这是我的纸模型课程

public class Paper {

public int primaryKey;

public String title;

public int entry;

public Boolean favourite;

public String comment;

public int opt;

public int score;
}

这是我的响应模型类

public class Response {

public List<Paper> papers;

} 

这是我的 JSON 字符串

我不知道我哪里做错了。我的论文列表为空。

使用流式解析器并尝试在读取完整输入之前处理您阅读的内容。这样你就可以避免将完整的结构保存在内存中。

例如，如果您的输入 JSON 是一个巨大的数组，您可以逐个元素地处理输入。
